Circular on Infrastructure and Amenities Charges for Mixed Building Proposals
The Tamil Nadu Town and Country Planning Department, through the Commissioner of Town and Country Planning, issued this circular dated 8 May 2013 to clarify infrastructure and amenities charges for plots containing multi storey buildings and other building types. It requires charges to be based on the total floor space index for the plot, the building categories and the proposed uses.
What the circular governs
The circular dated 8 May 2013 explains how infrastructure and amenities charges must be calculated when one plot contains a proposed multi storey building together with special or ordinary buildings. It was sent to all Regional Deputy Directors and the Member Secretaries of all Composite Local Planning Authorities and New Town Development Authorities, with instructions that the clarification must be followed.
Infrastructure and amenities charge rates differ according to building category, use, such as residential or commercial, and the area of the State.
Floor space index principles
The floor space index, or FSI, for a plot is calculated by combining the floor area of the proposed multi storey building and all other proposed buildings on that plot.
Key points are:
- For a proposal that is not in the multi storey building category, the maximum permitted FSI is 1.5, excluding the additional 20 per cent FSI available where stilt floor parking is proposed.
- FSI above 1.5, up to a maximum of 2.5, can be allowed only when a multi storey building is proposed on the plot.
- Where the combined FSI exceeds 1.5, all buildings on the plot are treated as receiving the benefit of the multi storey building provisions.
How charges are calculated
For a plot containing one or more multi storey buildings together with special or ordinary buildings, where total FSI exceeds 1.5:
- The multi storey building infrastructure and amenities charge rate applies to the entire FSI area on the plot.
- If different uses are proposed in different buildings or floors, the floor area for each use must be charged at the multi storey building rate prescribed for that use.
Where total FSI is 1.5 or less:
- Charges must be calculated separately for each building block.
- A multi storey building is charged at its applicable rate.
- Special and ordinary buildings are charged at the special building rate.
Economically weaker section housing
Where all or part of the required 10 per cent housing for economically weaker sections is proposed on another plot within five kilometres of the main plot, the same calculation method applies if that other plot contains multi storey and other building types. If the other plot contains only a special building, the special building rate applies.

Common questions
How is FSI calculated when one plot has several building types?
The floor areas of the multi storey building and all other proposed buildings on the plot are combined to calculate the plot's FSI.
What charge applies if a mixed building proposal has FSI above 1.5?
The multi storey building infrastructure and amenities charge rate applies to the entire FSI area. Where there are different uses, each use is charged according to its floor area and the applicable multi storey rate for that use.
What happens when the total FSI is 1.5 or less?
Charges are calculated separately for each building block. The multi storey building uses its applicable rate, while special and ordinary buildings use the special building rate.
Can economically weaker section housing be provided on another plot?
The circular covers proposals placing all or part of the required 10 per cent economically weaker section housing on another plot within five kilometres of the main plot. The charge depends on whether that plot contains mixed building types or only a special building.
